What Is Squalane?

What is Squalane?

Squalane is a clear, odorless, tasteless, non-toxic and non-irritating oil that is naturally present on skin as a minor component of sebum (around 2-3%). Sebum is the oil-like substance produced by the skin’s sebaceous glands that makes hair look shiny and prevents skin from becoming dry and itchy. Sebum, along with water from environment and sweat, forms a surface barrier protecting the skin from excessive water loss and the detrimental effects of pollutants, sun, and ozone [1]. Sebum is composed of triglycerides and free fatty acids (57.5%), wax esters (26%), and squalene (12%) [2] . We do not want to use extra squalene (with an “e”) to help moisturize our skin, because squalene easily oxidizes to peroxides that can induce comedogenesis (clogged pores) and inflammation [1]. The chemical structure of squalane, on the other hand, is very stable and cannot be naturally oxidized. Squalane then is a brilliant natural moisturizer and emollient to prevent water loss and maintain skin’s suppleness and flexibility.

Why Your Skin Will Love Squalane...

By acting as an emollient, squalane functions to soften dry, rough, flaky skin, making skin look healthier and feel better. When the top layer of skin doesn’t contain enough water, it dries out. Drying causes skin to crack and flake off, leaving open spaces between the cells in your skin. Emollients fill those spaces with fatty substances, like squalane, which make your skin look and feel smoother and softer and your hair look more shiny. Squalane also works to keep skin hydrated by forming a protective barrier to retain the natural moisture in skin preventing it from drying out.

Is Squalane Safe?

Squalane is nontoxic and non-irritating at levels up to and including 100% purity [3] . Squalane is ECOCERT certified and is listed in the EPA’s Safer Choice Chemical Ingredients list [4], ensuring that it is one of the best and safest possible emollients to use on a daily basis.

Is all Squalane the Same?

Technically speaking yes, in that the chemical structures are the same, however, the source material used to manufacture squalane is highly variable which can result in unwanted impurities and depletion of our natural resources.

Our 100% plant-derived squalane is sourced from fermentable sugars in sugarcane, an agricultural crop that is totally biorenewable and sustainable. Production from sugarcane does not harm the environment or deplete natural resources like chemically synthesized squalane or squalane or derived from shark liver. The squalane produced from sugarcane is highly pure and does not contain environmental pollutants like those from shark liver oil.

Squalane derived from sugarcane then, passes our high internal quality and environmental sustainability standards that you come to expect from skincare products of exceptional quality. No animals were used in the manufacture and/or testing of our products.
